Pyston claims 30% performance improvement over cpython while maintaining compatibility, pypy claims it's 4.2x faster but has some compatibility issues irrc.
- tempay 5y agoIt's pretty good in terms of compatibility these days. Conda-forge has builds of most packages available for both cPython and PyPy on macOS/Linux/aarch64/ppc64le: https://conda-forge.org/status/#pypy https://conda-forge.org/status/#pypy
- viraptor 5y agoPypy's claim comes from a set of common Python benchmarks. Pyston claim comes from company's webserver benchmarks. These may be comparable, but may be also apples-to-oranges.
- kmod 5y agoWe use completely separate benchmarks, where our Pyston benchmarks are quite a bit "harder" and PyPy is only 12% faster on them while using 4x the memory.
